Production Processes of Lab Grown Pink Diamonds

HPHT method of making lab grown diamonds.

Lab grown pink diamonds are meticulously created through sophisticated technological methods, each ensuring that the final gem meets high standards of quality and color. These diamonds are crafted in controlled environments using predominantly two methods: Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT), both of which are designed to replicate the natural growing conditions of diamonds.

Chemical Vapor Deposition (CVD)

The CVD process begins by placing a thin slice of diamond, known as a seed, in a sealed chamber. The chamber is then filled with a carbon-rich gas mixture, typically methane and hydrogen. When the gases are heated to extremely high temperatures, they begin to break down, allowing carbon atoms to adhere to the diamond seed. Over time, these atoms build up in crystalline layers to form a diamond. Your lab grown pink diamond emerges from a highly controlled environment, where factors like temperature, pressure, and gas composition are carefully managed to ensure the desired pink hue.

High Pressure High Temperature (HPHT)

HPHT simulates the natural conditions under which diamonds are formed deep below the Earth's surface. In this method, a small diamond seed is placed within a piece of carbon, usually graphite. This assembly is then subjected to temperatures in excess of 1400°C and pressures above 5 GPa. Through this process, the carbon melts and starts to form a diamond around the seed crystal. The conditions to produce a pink diamond via HPHT are incredibly precise, necessitating exacting control over every aspect of temperature and pressure to achieve the signature color.
